My Baby Has a Strawberry Hemangioma
A strawberry hemangioma is a bright red, raised birthmark made of extra blood vessels. It typically appears in the first few weeks of life, grows for several months, and then slowly shrinks and fades over several years. Most hemangiomas are harmless and do not require treatment, though your pediatrician will monitor growth and location.
My Baby Can't Figure Out How to Use a Straw Cup
Learning to drink from a straw is a new skill that takes practice. Most babies can learn between 6 and 12 months. You can teach by placing a straw in liquid, covering the top to trap liquid, and releasing it into baby's mouth. Some babies learn quickly while others need weeks of practice.
Sturge-Weber Syndrome in Babies
Sturge-Weber syndrome (SWS) is a rare neurocutaneous disorder involving a port-wine stain (capillary malformation) on the face, a vascular malformation on the brain surface (leptomeningeal angioma), and/or glaucoma. It is caused by a somatic GNAQ gene mutation and affects approximately 1 in 20,000 to 50,000 births. Not every child with a facial port-wine stain has SWS — the risk is highest when the birthmark involves the forehead and upper eyelid. Early diagnosis with brain MRI and eye examination allows for proactive seizure management and glaucoma screening, which can significantly improve outcomes.
Toddler Stuttering or Stammering
Developmental stuttering - repeating sounds, syllables, or words - is very common in toddlers between ages 2 and 5, occurring in about 5-8% of children. In most cases it's a temporary phase that resolves on its own as the brain catches up with rapid language development. About 75-80% of children who stutter will stop naturally.
Subchorionic Hematoma
A subchorionic hematoma (SCH) is a collection of blood between the uterine wall and the chorion (the outer membrane surrounding the embryo). It is the most common cause of first-trimester bleeding and is found in about 1-3% of pregnancies. Most subchorionic hematomas are small, cause no problems, and resolve on their own. The majority of pregnancies with SCH result in healthy babies.
Subconjunctival Hemorrhage in Newborns
A subconjunctival hemorrhage is a bright red patch on the white of the eye caused by a small broken blood vessel under the conjunctiva (the clear membrane covering the eye). This is very common in newborns, occurring in up to 30-40% of vaginal deliveries due to pressure during birth. It is painless, does not affect vision, and resolves completely on its own within 1-3 weeks without any treatment.
Subgaleal Hemorrhage
Subgaleal hemorrhage is a rare but serious condition where blood collects in the potential space between the scalp's connective tissue layer (galea aponeurotica) and the periosteum of the skull. Unlike caput succedaneum or cephalohematoma, subgaleal hemorrhage can cross suture lines, increase rapidly in size, and cause significant blood loss. It is a medical emergency that requires immediate hospital monitoring and treatment.
Subglottic Stenosis (Narrowed Airway Below Vocal Cords)
Subglottic stenosis is a narrowing of the airway just below the vocal cords. It can be congenital (present from birth) or acquired, most commonly following prolonged intubation in premature or critically ill newborns. Symptoms include biphasic stridor (noisy breathing on both inspiration and expiration), recurrent or severe croup episodes, and exercise intolerance. Mild cases may be monitored as the child grows and the airway widens, while moderate to severe cases may require surgical intervention such as endoscopic dilation or open airway reconstruction.
Sudden Unexpected Infant Death (SUID): Prevention Strategies
Sudden Unexpected Infant Death (SUID) includes SIDS, accidental suffocation in a sleep environment, and other unexplained deaths. About 3,400 infants die from SUID annually in the US. Following AAP safe sleep guidelines can significantly reduce the risk: always place babies on their backs to sleep on a firm, flat surface; share a room but not a bed; remove all soft bedding, pillows, and toys from the sleep space; avoid overheating; offer a pacifier at sleep time; and maintain a smoke-free environment.
Sugar Intake Concerns for Babies and Toddlers
The American Heart Association and the AAP recommend that children under 2 years of age consume no added sugars at all. Added sugars provide empty calories, displace nutrient-dense foods, and establish a preference for sweet tastes that can lead to unhealthy eating patterns, obesity, and dental caries. Natural sugars found in whole fruits, vegetables, and plain dairy are fine and are part of a healthy diet.
My Baby Got a Sunburn
Baby skin is much thinner and more sensitive than adult skin, so sunburns can happen quickly even on cloudy days. A mild sunburn will appear as pink or red skin that feels warm to the touch and typically heals within a few days. Keep your baby out of direct sun, apply cool compresses, and ensure they stay well hydrated while the burn heals.
Sun Damage and Freckling in Toddlers
Freckles in toddlers are a sign that the skin has been exposed to enough ultraviolet (UV) radiation to stimulate extra melanin production. While a few freckles are common in fair-skinned children, the appearance of new freckles means the skin is being exposed to more sun than it should be. Childhood sun exposure is a significant risk factor for skin cancer later in life, so sun protection habits established early are essential.
Sunscreen for Babies Under 6 Months
The AAP recommends avoiding sunscreen on babies under 6 months when possible, as their skin is thinner and absorbs chemicals more readily. The primary protection should be shade and protective clothing (long sleeves, wide-brimmed hat, UV-protective fabric). However, if shade and clothing are not available and sun exposure cannot be avoided, a small amount of mineral sunscreen (zinc oxide or titanium dioxide) on exposed areas is considered safe and is preferable to sunburn.
Supernumerary Teeth (Extra Teeth in Babies and Toddlers)
Supernumerary teeth are extra teeth beyond the normal set (20 baby teeth or 32 permanent teeth). They occur in approximately 1-3% of children and are more common in boys. The most common type is a mesiodens, an extra tooth that appears between or behind the two upper front teeth. Supernumerary teeth may not cause any problems, but they can sometimes prevent normal teeth from erupting, cause crowding, or lead to cyst formation. Diagnosis is typically made by dental X-ray, and treatment depends on whether the extra tooth is causing or is likely to cause complications.
Breast Milk Supply Dips at 3, 6, and 9 Months
Perceived dips in breast milk supply around 3, 6, and 9 months are extremely common and are usually caused by your body becoming more efficient at producing milk rather than an actual decrease in supply. Your breasts may feel softer and less full, and letdowns may feel less noticeable, but these are signs of a well-regulated supply. True low supply is uncommon when feeding on demand.
Supraventricular Tachycardia (SVT) in Babies
Supraventricular tachycardia (SVT) is the most common abnormal heart rhythm in infants and children. During an episode, the heart rate can reach 220-300 beats per minute in infants, compared to a normal rate of 100-160. Babies may become pale, irritable, or lethargic, and may feed poorly. Most episodes can be stopped with vagal maneuvers or medication, and many children outgrow SVT by age 1. If your baby appears pale, fussy, or you feel an extremely fast heartbeat, seek immediate medical attention.
Sweating During Feeding as a Heart Sign in Babies
Sweating during feeding (diaphoresis) in a baby can be a sign of an underlying heart condition. For a baby with a heart problem, feeding is like exercise -- it requires significant effort, causing the baby to sweat, breathe rapidly, and tire easily. While some sweating during feeds can be normal (especially in a warm room or when bundled), persistent sweating along with rapid breathing, taking longer than 30-40 minutes to feed, poor weight gain, or frequent pausing during feeds can indicate that the heart is working too hard. If your baby consistently sweats during feeds and has any other concerning signs, discuss this with your pediatrician.
Switching Formula Brands
Switching formula brands is generally safe and does not require a gradual transition. All standard infant formulas sold in the United States must meet the same FDA nutritional requirements, so your baby is getting comparable nutrition regardless of brand. Some babies adjust immediately, while others may have a few days of slightly different stools or minor fussiness. If your pediatrician has recommended a specialty formula, follow their specific guidance on switching.
My Baby Has Swollen Glands
Swollen glands in babies most commonly refer to enlarged lymph nodes, which are a normal immune response to infections. Salivary gland swelling is less common in babies but can occur. Lymph nodes in the neck, behind the ears, and in the groin are frequently palpable in healthy children and usually indicate the immune system is working properly. Most swollen glands resolve on their own as the underlying infection clears.
My Baby Has Swollen Lymph Nodes
Swollen lymph nodes are very common in babies and young children and are almost always a sign that the immune system is doing its job fighting off a minor infection. Small, pea-sized, rubbery, moveable lymph nodes in the neck, behind the ears, or in the groin are normal findings in healthy children. They rarely indicate anything serious.
Symphysis Pubis Dysfunction (SPD/PGP)
Symphysis pubis dysfunction (SPD), also called pelvic girdle pain (PGP), occurs when the joint at the front of the pelvis becomes too loose during pregnancy, causing pain, instability, and difficulty walking. It affects about 1 in 5 pregnant people to some degree. It is caused by the hormone relaxin and the weight of the growing baby.
My Baby Has Webbed Fingers or Toes (Syndactyly)
Syndactyly (webbed or fused fingers or toes) is one of the most common congenital hand and foot differences, occurring in about 1 in 2,000-3,000 births. It can be simple (just skin connecting the digits) or complex (bones or other tissues fused). Webbed toes often require no treatment and do not affect function. Webbed fingers, particularly those involving the thumb or ring/small fingers, are typically treated with surgery to improve hand function. The timing and approach depend on which digits are affected.
Syphilis Screening During Pregnancy: Why It Matters
Syphilis screening during pregnancy is critically important because congenital syphilis (transmitted from parent to baby) has increased dramatically in the US, rising over 900% from 2012 to 2022. Untreated syphilis during pregnancy can cause miscarriage, stillbirth, preterm birth, and serious complications in the newborn. The good news is that syphilis is completely treatable with penicillin, and treatment during pregnancy prevents transmission to the baby in almost all cases. All pregnant individuals should be screened, with repeat screening recommended in high-prevalence areas.
Tablet Dependency in Toddlers
Tablets are particularly compelling for toddlers because of their interactive, touch-responsive nature. When a toddler relies on a tablet to eat, sit still, or cope with any frustration, it can prevent them from developing important self-regulation skills. The AAP recommends limiting all digital media to 1 hour per day for children ages 2-5. If your toddler seems unable to function without a tablet, gradual reduction paired with engaging alternative activities is the recommended approach.
